Architecture of NewtApp

Application Layer

This layer handles application-wide things, such as:

Registration/Unregistration
For various system services such as find and soup change notification.

Application state
Applications on the Newton should save their state on close and restore that state on open. This way, an opened application looks as it did when it was last closed.

User preferences
The application layer handles preferences and is responsible for getting and maintaining relevant user information.

About Slip
Where programmers indulge their egos, as well as provide version and copyright information.

Switching between views
This handles the overview button to switch between overview and detail layouts.
